Hallucinating whilst falling asleep

I keep having a problem where I’m trying to fall asleep and whilst my eyes are closed, I’ll subconsciously picture the surroundings in front of me and think that my eyes are open which makes me open them for real and gives me a hard time falling asleep. I don’t know why this happens as it’s not like I think about my bedroom or anything, I just imagine it out of nowhere. I do have an active mind at night and often find myself having to repeat the word “sleep” in my head and focus on it so every other thought disappears.. but I can’t find any ways to stop imagining my room. It’s not like I know I’m imagining either because I see it so vividly that my half asleep brain believes it and wakes up for real. Does anybody know anything I can do to help?🙏
